Emily Strong—a PhD student at the University of Sheffield who regularly updates her own blog and describes herself as a lover of “all things Harry Potter” in her Twitter bio—tweeted the solution at the Harry Potter author on Tuesday afternoon: “Newt Scamander only meant to stay in New York for a few hours.”

The anagram, according to TIME’s own interactive anagram solver, does indeed check out. It’s a reference to Fantastic Beasts and Where to Find Them, a Harry Potter spinoff that will soon hit the big screen as a trilogy.

Despite saying in her initial tweet that she was busy working on a novel and the screenplay for Fantastic Beasts, Rowling chimed into Twitter throughout the last day offering hints (“The solution is the first sentence of a synopsis of Newt’s story”) and rejecting wrong answers. Though fans thought the author might be hinting at more Harry Potter books, alas, she did not confirm a return of The Boy Who Lived.

After congratulating Emily Strong on unscrambling the anagram, Rowling thanked everyone for participating:

Thank you, thank you, for being the kind of people who get excited about an anagram #myspiritualhome
